Red light therapy started in clinics — courses of in-office sessions under professional panels. The at-home category exists because the light source is the treatment: put the same wavelengths in a consumer device, accept lower power and longer timelines, and the economics flip from hundreds of dollars per course to one purchase you keep.
Clinic vs home, honestly compared
Clinic panels run at higher output with professional protocols — they get where they're going faster. Home devices are lower-powered by design (they have to be safe without supervision), so they lean on consistency instead: more sessions, more weeks, same direction of travel. Neither is "better"; they're different trade-offs of money, time and discipline. What kills results at home isn't the hardware — it's the drawer. A device used twice does nothing.
Choosing a home device without getting burned
- Insist on the proven wavelength pair — red ~630–660nm plus near-infrared ~830–850nm. This is the combination the cosmetic evidence base is built on.
- Look for published irradiance (mW/cm², ideally with the measurement distance stated). Most brands don't publish it. The $50 marketplace masks that look identical to $500 ones usually differ exactly here — same colours, fraction of the output.
- Check the safety paperwork — IEC 62471 is the photobiological (eye) safety standard; eye protection in the box is a good sign. In Australia, be sceptical of "TGA approved" phrases without an ARTG number you can check.
- Warranty tells you what the maker believes — 2 years says more than any testimonial.
A realistic home protocol
- Clean, dry skin — no SPF or makeup layer between light and skin.
- Eye protection on, device on. Sessions are typically 3–10+ minutes depending on the device's output; follow its stated protocol rather than doubling up ("more" doesn't scale the way you'd hope).
- 3–5 sessions a week. Anchor it to an existing habit — kettle, podcast, skincare routine.
- Take a photo in consistent light before you start, and judge at week 8, not day 8.
Who should check with a doctor first
Anyone on photosensitising medication (some antibiotics and acne treatments), anyone pregnant, anyone with a photosensitive condition, eye condition or recent eye surgery, and anyone with a history of skin cancer on the face. Not because home devices are wild west — because those are exactly the situations the studies didn't cover.
A note you will find at the end of every Rosalume article: changes in skin appearance from light therapy build over 8–12 weeks of consistent use, 3–5 sessions a week. They are gradual, not dramatic. Any brand — including ours — promising more than that is selling, not informing.
